(National Sentinel) Domestic Terrorism: A website supportive of the far-Left group Antifa has deleted a post about sabotaging trains following the deadly derailment on Monday of an Amtrak commuter train in Washington, in which six people were killed.

As noted by The Gateway Pundit, the original article was published in April. However, a more recent post from another far-Left group possibly linked to Antifa published another story just a few days ago, and it remains online.

The Amtrak derailment comes after Antifa members sabotaged a train in Olympia, Wash., in November, which led to a police raid of their encampment.

Protesters had been blocking the tracks for a week after preventing the train from leaving the Port of Olympia on Nov. 11, The Olympian reported. The train was carrying fracking materials.

Earlier this year, a prominent Antifa-related website published an article tacking credit for the sabotage of train tracks in Olympia, WA. In the article they claimed to have poured concrete on the tracks. It has since been deleted, tweeted Far-Left Watch.

A website belonging to Puget Sound Anarchists published a post Dec. 9 claiming that members attempted to sabotage rail lines in Washington:

During this week we attached wire and jumper cables to the main Union Pacific rail line running through the state of Nebraska to disrupt rail signals and delay trains that mainly carry coal from the mountainous west to population centers in the east.

Inspiration for us came from the blockade in Olympia, Unist’ot’en camp in unceded Wet’suwet’en territory, and other actions large and small across turtle island.

In April the group Itsgoingdown.org published a post claiming that group members attempted to sabotage tracks near Olympia. That post has since been removed.

But archived copies of the post noted:

Early in the morning of April 20th we poured concrete on the train tracks that lead out of the Port of Olympia to block any trains from using the tracks. We took precautions to notify BNSF (the train company) – we called them and we used wires to send a signal that the tracks were blocked. We did this not to avoid damaging a train, nothing would bring bigger grins to our faces, but to avoid the risk of injuring railway workers.

This action was done to disrupt the movement of trains carrying proppants used in natural gas fracturing. These train tracks are part of a system of pipelines, fracking wells, mines, clearcuts, control centers, fiberoptics, dams, highways and factories that cover the planet and are physical manifestations of a process that is destroying the ecosystems, cultures, and inhabitants everywhere.

In August, the Transportation Security Administration warned that international terrorist group Al Qaeda was urging attacks on Western rail service, especially in the United States.

Al Qaeda’s newly released online propaganda magazine “Inspire” featured a cover story under the headline, “Train Derailment Operations,” in which the group described how to sabotage rail lines, particularly those used by Amtrak.

The terrorist publication, considered a handbook for many radicals who actually carry out attacks, listed dozens of “vulnerable” train routes in the U.S. as potential targets, noted ABC7.

“TSA is aware of the recent Al-Qaeda threat to rail systems, and this past Friday issued a message to our transportation partners,” said agency spokesperson Michael McCarthy.
